fn 1411.31 buss 12E, which forms a hearing for, and loosely receives theshank 16 on the tapered spindle head 16, see Fig. Il. The shank 16 bearsat its vinner end, preferably against a ball 17 within the boss 12, andsaid shank 1(3 is provided with an annular groove or recess 16, intowhich extends the end of a set screw 18, which turns in a threaded holein the boss 12, and prevents thespindle 16 from moving longitudinally. Asecond spindle with a tapered head 19 is suitably journaled in a boss orbearing 2O on the arm 3, and is of the same construction as the sp2'`dle 16. Both the tapered spindle heads 16 and 19 are revolubleindependently of each other with the spool.

A yarn spool 21, having in this instance a central opening 21therethrough, and carrying the yarn 22, is held between the two taperedspindle heads 16 and 19, and can be readily put in place or removed,by'moving the holder 12, through the releasing of the engagement of thecam shaped. extension 14" oir the arm 14, with ihe rod 11', as abovedescribed.

The thread tension device consists in this Yinstance of an arm 23 havingan elongated hub 23 thereon, which is loosely mounted set screw 27 onthe rod 10.

on the upper horizontally extending rod 10. An arm 23, extendingupwardly from the hub 23, 'carries a horizontally extending wire 24.. Ahelically coiled torsion spring 25 encircles the hub 23 on the arm 23,and is connected at one end to said arm 23, and at its other end to acollar 26 secured by a n the arm 23 is a pad 22, which is adapted tobear against. the thread or yarn 22 on the spool 21 to act as a frictionon the spool, the torsion spi/mg 2.? acting to yicldingly press the pad2o against the yarn or thread 22.

A second arin 28 has its hub 28 loosely mounted on 'the rod 10. frcollar 29 is se cured on the hub 28 by a set screw 3l) and has connectedthereto one end oi' a coiled torsion spring 31. The other end of saidspring 31 is attached to the arm 23. Said spring 3l. acts to yieldinglyniove upwardl)w the. arni 2S until it engages the wire. 2l extending outfrom the extension 23 on the arn'i 23. 'llie engagement of the arm 2Swith the wire 2A, causes the pressure ol the friction pad 23 on the yarnor thread 22 to be increased.

Secured lo the outer end ot' roeoee the arm 28 is a Wire 32, aroundWhich the thread 22 passes, see Fig. 2. rlhe tension or pull on thethread 22 in unwinding the thread from the spool 2,1, causes thedownward movement of the Wire 32, and also the arm 28, and disenga gessaid arm 28 from the wire 24, to decrease the friction or pressure ofthe pad 23 on the yarn or thread 22.

The wire. 32 over which the thread from the spool passes acts asa guidefor the thread, and extends parallel to the spool, and is preferably ofa length equal to the length of the spool, so that the thread as itisunwound or drawn oil from lthe spool, will extend in a substantialvertical plane. In unwinding or drawing the thread from the spool,through a guide eye, as is cusn tomary, the thread is liable `t'Qlfiecut or broken, but drawing it over the guide Wire or rod 32,' the threadYis free to travel in the direction ot' the length'of said guide wire orrod, and is not liable to be chafed or broken. The advantages of myimprovements will be readily appreciated by those skilled in the art.They are very simple in construction and can be readily applied toWinding machines of ordinary construction.

It will be understood that the details of Vconstruction of myimprovements'may be varied if desired. l have shown and dcscribed hereina spool 21 on which the yarn is wound, out it will be understood that acop, a cylinder orother device, may be used if preferred.

Having thus described my inventioinwliat I claim as new and desire tosecurefloy lire-tn ters l)atent is ln a winding machine ot the classdescribed, a spool from which the thread is to be uiiwouiid, twosupporting revoluble spindles, one movable longitudinally, a -liriclionpad to bear against the thread on the spool, a spring connected to said`pad, tov

cause the same to he pressed against said thread, a rod or guide overwhich the thread passes trein the spool, a second spring connected tosaid rod or guide, and to said friction pad, whereby the tension of thethread over the rod or guide lessi-ins the pressure ot the friction padon the thread.
